I am looking for a book that I had started many years ago as a tween but have since forgotten the title. I never finished it, but what I can remember was that it had a dark (possibly black) cover. In terms of plot I believe it had something to do with mysterious disappearances, where people where inexplicably called or lured into the sea and never seen again. I believe it was set in New England in a coastal town. It would have been a hardcover around the time of 2000-2005. I think there was something about a man and his father having gone into the ocean. Maybe a sea monster? I didn’t get far enough into the story to figure out why the people were disappearing. I believe it was a book for adults. I don’t think it was part of a series. The time period was modern. I don’t know if it was mystery or horror, as I never finished it. I think it might’ve been classified as mystery. I don’t think it was a young adult book and I believe it had a male author
